货币升值想要减少贸易盈余的被后逻辑是，因为本国货币升值，本国商品更贵了，外国商品便宜了。这时候本国居民就会购买更多的国外商品，外国居民会减少对本国商品的购买。一旦本国购买外国的商品市值超过外国购买本国商品的市值（资本进入本国市场），贸易盈余便开始减少。但是如果上述临界条件没有达到。即在本国货币升值情况下，本国购买外国的商品市值依然小于等于外国购买本国商品的市值，那么贸易盈余情况就不会得到改善。
那么如何判断本本国购买外国的商品市值大于还是小于外国购买本国商品的市值，关键就是看资本流向。国外买的本国市值超过本国买国外市值的时候，净资金流应该流入国内。这就是C选项表达的意思。

那么老师，c选项不也是说国际资本往国内流入吗

NO.PZ2016010802000219 经常性账户盈余意味着出口＞进口，即经常性账户有钱流入，为了保持国际收支平衡，需要资本账户的钱流出。如果按照答案所说，资本账户钱再流入本国，那么不就会导致国内钱太多，而导致本笔升值而无法达到平衡吗？ 请老师帮看看，这样理解是哪里出现了问题？
